3DR telemetry no longer supported by 3DR....options?

I have been using the 915mhz telemetry v2 units with my Pixhawk for a while now.  One of them is not giving the range that it used to and I need a replacement.

I varified the range with the use of my Fighting Walrus iDrone Link and one unit is getting about 100m range while the other is getting good signal to where my hexacopter is just a spec in the distance.

Problem 1:

I can not get hold of Fighting Walrus any more.  They have not answered my emails since about October of 2015.  I am assuming they are no longer active? (also no updates to their iOS app for almost a year)

Problem 2:

3DR are no longer making their 900 or 433 telemetry units. (verified vie an email to them)

"Hello Justin,

Thank you for contacting 3DRobotics customer service.

We apologize for the inconvenience. Unfortunately, we do not have the Telemetry available anymore since they have been discontinued, both the 915 and 433."

I am using a Nexus 7 v2 Tablet with the Tower App (great app by the way)


Other than the $250 long range 900mhz kits (I don't need/am not allowed to use super long range) or $10 knock 3DR off kits from China (gamble as to whether you get a good one/no warranty), what options are there that are "PnP" ?

I am using a Taranis Plus TX with x8r RX and could use that telemetry but then there is no way to load missions in the field.

Thanks for input

Horrible :O 

One option available that is relatively inexpensive is the RFD900u modems:


A pair of these is around $98 USD with the current exchange rate!

Good thing is these have filtering, low noise receive LNA and diversity antennas and are smaller than the 3DR modules!

The current version of the RFD900+ is available in a bundle:


With the current exchange rate, $229.95 AUD is around $161 USD.

Hope it helps with some options!

Or if you want hassle free fully assembled sets. You can get those from jDrones store. We are Seppo's original distributor but our telemetry systems are not just telemetry modems, they are whole set with cabling, casing, adapters and filtering electronics.


We also have older SiK modems but for reliability we prefer RFD kits.

Craig,  I am not promoting RTF quads.    However the 3D Robotics web store no longer carries the 3DR-radio-telemetry kits.   So my choices for low cost telemetry radios are now RTF Quads or HK.   I will get some of both.

So long as you understand that the reason you can no longer buy radios in the 3DR store is because of people buying them from companies like readytoflyquads who have never contributed to the development.

You can buy the Sik radio Jdrones and like I said elsewhere Jdrones is a supporter of this project.

for anybody looking for the original 3DR modules - we still got some 3DR 433 telemetry modules in stock at http://www.uav-store.de/

you can still get the telemetry clone from ebay, just change the tx that comes with the clone.

If you're worried about quality from other sources, you can build them from scratch yourself. All of this is open source.  Better yet, start a company that produces and sells the products you want and see how long you stay in business.  3DR would not be doing this if the diy parts were profitable.  HK makes some extremely good products and the 3DR telemetry clones are very good.

The hobby multirotor market would not be nearly where it is if it weren't for 3DR.  They are not abandoning anyone.  They continue to lead the development of the hobby and the commercial side.

Be awared that majority of the clone telemetry kits does not work with the iris original telemetry tx. Hence, you need to replace the iris telemetry tx. Also the telemetry receiver for the remote radio. 


It looks as though luck was on your side with the cheap China $10 to $15 units.  I have tried some from eBay and Bangood.  This was also part of my original question.  Where to get good quality (not "let's take a gamble") parts.

Your price is right but not the parts....... for me that is.  My DIY Hex cost me a pretty penny.  I would rather not have it crash due to a $10 clone.
